Default Reset HVAC? Reading wrong temp

I recently bought an 03 coupe, and the HVAC has shown 69 degrees outside, when it is over 100 here. Any ideas? Reset the HVAC? Thanks in advance....

Look at the outside temp sensor located on the passenger front of the car next to the radiator. Looks like a small black probe. You can see it with the hood up, looking between the hood and bumper cover. I replaced the one on the '99 I just bought because it showed 57 degrees all the time (in August in Alabama), and it fixed it. Eleven bucks at the local CARQUEST; not much more at the dealer. Drove it a few miles to reset everything, and the A/C was back to normal.

before you buy a new one check the connections on that one and try disconnecting the battery for a few minutes....did that to reset mine.....all that costs is 5 minutes.

Well I reached my hand down in there, and it was unplugged! Will it take some driving to relearn? I had 3 HVAC codes I could not clear obviously because this was unplugged.

Mine started up and fixed itself, but I've heard of people having to drive it some and it would relearn.
